+ @ROUT cputhrottle.txt
+ It appears that your Operating System is doing CPU throttling. Because
+ the OS adjusts the Mhz of the CPU as things are running, timings become
+ extremely unreliable. An ATLAS install, therefore, is completely useless
+ (ATLAS makes optimization decisions on essentially random data). Therefore,
+ you need to disable CPU throttling before continuing the install. On most
+ machines this may be done by changing the BIOS settings (eg., on my Athlon-64
+ machine, I can say "No" to "Cool and Quiet" under "Power Management").
+ Alternatively, most operating systems allow you to set it yourself. Under
+ many Linux distros, a command similar to this will work:
+ /usr/bin/cpufreq-selector \
+ -f `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
+ Under MacOS or Windows, you may be able to change this under the power settings.
+ In any case, either change this using your OS or BIOS, and try again, as ATLAS
+ cannot achieve a valid install in the face of CPU throttling.
